On Wednesday, top trade officials from the U.S. met with their EU counterparts in Paris as a temporary exemption from the tariffs was set to expire.

In recent days, trade negotiations showed few signs that the two sides would reach an agreement. European officials have said that they expected the U.S. to follow through with imposing tariffs.

While the European Parliament would like a result with no tariffs or quotas, European Commissioner for trade Cecilia Malmström said Tuesday, "Realistically, however, we do not think we can hope for that."

Late Wednesday, a European Commission spokesperson declined to speculate on what the United States' final decision will be.
